Axial T1

Atrophy of the right cerebral hemisphere with exvacuo-dilatation of the right lateral ventricle. Associated enlargement of the right frontal and sphenoidal sinus compartments as well as relative thickening of the right side of skull vault with relatively much bone marrow seen compared to the left side. Subtle right side falcine displacement is also seen

The prersence of calvarial changes suggests the diagnosis of Dyke Davidoff Mason syndrome
